Abstract (en)
[origin: WO2010052372A1] A circulating fluidized bed boiler (10), comprising a furnace (12) for combusting carbonaceous fuel, at least one outlet channel (14) connected to the upper portion of the furnace for removing flue gas and solid particles generating in the combustion of fuel, each outlet channel provided with a particle separator (16) attached with a flue gas channel (18) for transferring cleaned flue gas and a return duct (20) for transferring separated solid particles to the lower portion of the furnace. The return duct is provided with a gas seal (22), a heat exchange chamber (24), a lift channel (34) and an overflow conduit (44), in which solid particles exiting the gas seal are guided to the upper portion of the heat exchange chamber (24) and from the lower portion of the heat exchange chamber through the lift channel (34) to the furnace or directly from the upper portion of the heat exchange chamber through the overflow conduit (44) to the furnace, and there is at least one downpipe (42), which is connected from the upper portion to flow connection with the upper portion of the lift channel (44) and from the lower portion to flow connection with the lower portion of the furnace and additionally the overflow conduit (44) is connected to the upper portion of the downpipe. The downpipe (42) is preferably also connected to an inlet for fuel (50).
